BMW Concept Z4: BMW’s roadster tradition, reloaded

A statement of unbridled driving pleasure.

The sporty and progressive BMW Concept Z4 encapsulates the BMW Group’s vision of a modern roadster. “The BMW Concept Z4 expresses the new BMW design language from all perspectives and in all details.

From the dynamic-looking front to the striking flanks to the clean-cut tail end: a few lines and the subtle interplay between surfaces are enough to generate a sense of power and emotion,” adds van Hooydonk.

BMW’s roadster tradition, reloaded.

The BMW Concept Z4 adopts classical roadster design cues, such as a long wheelbase, a low-slung, stretched silhouette and a compact rear end, wraps them in a fresh, confident package and enriches them with the contemporary BMW design language.

The large domes stretching out rearwards from the cabin elegantly integrate the function of rollover bars and provide a sporting conclusion to the low-to-the-road silhouette at the rear.

Reimagining the design language and surfaces.

The clearly sculpted shark nose at the front end spawns dramatic surface contouring that extends the full length of the flanks. The new direction taken by BMW’s design language can be seen here in just a few precise lines that form clear surfaces, while the body’s volumes are powerfully sculpted. The surfaces and forms therefore create an extremely modern and emotionally engaging impression.

The large Air Breathers rearwards of the front wheels act as the source of the flanks’ elaborately modelled surfaces (they appear to be shaped by the flow of air as it exits the Air Breathers). Light and shaded surfaces develop in a rising movement towards the rear, then twist to form muscular wheel arches and athletic volumes.

All of which shines a bright stylistic spotlight on the car’s rear-wheel drive. The dramatic interplay of lines and surfaces underscores the wedge shape of the flanks and infuses them with even greater dynamism. And the low door sills, with their distinctive crease, makes the body appear closer to the road, emphasising the low-slung sensation when viewing the car from the side.
